Invertebrate Surveys

Invertebrate surveys are normally required where their potential presence has been identified in a previous survey, or where requested by the Planning Authority. We are able to undertake invertebrate surveys and assessments for many of the main invertebrate species groups.

Invertebrate Legislation

There are only a few legally protected invertebrates in the UK, however a significant number are listed on the UK Biodiversity Action Plan (BAP) and on many Local Biodiversity Action Plans (LBAP), such as the stag beetle on the London BAP. Many are associated with brownfield development sites or urban areas.

Invertebrate Seasonal Constraints

Surveys for invertebrates are generally species specific. However, as a guide, surveys for terrestrial invertebrates are normally undertaken between April and August, with surveys for aquatic invertebrates undertaken between March and August. Please contact us if you would like to know specific survey periods for a specific invertebrate species.

Invertebrate Survey Methods

Surveys for invertebrate species are generally unique to the individual species, depending on their lifecycle and habitat. Common groups that are often required for assessment include butterflies, moths, bees and wasps, various fly families and also beetles. We have particular experience of undertaking surveys for stag beetles.

Invertebrate Mitigation

Mitigation for invertebrates is again species specific, but is generally more straightforward than for the other protected species and can be tied into schemes for other species which share the same habitats as many scarce invertebrates, particularly on brownfield sites.
